Romberg POPUP BOX Potting Soil - Growing Medium
Compacted substrate with Romberg POPUP BOX
The Romberg POPUP BOX is a compaction substrate suitable for sowing, propagation and growth of young plants. Compacted substrate gives an opportunity to store and prepare growing substrate without using unnecessary volumes of it. After soaking with water, it gets prepared for usage.
Practical compact substrate
As it is seen from its name, the Romberg POPUP BOX is supplied in a compacted form and takes up less volume. In case you have to organize propagation substrates, then the compacted substrate gives you the opportunity to do it within the limited space. After soaking the substrate with water it transforms into a loose growing substrate.
This kind of substrate is suitable for smaller propagation setups and seed growing, when there is a need to use small quantities of substrate. Prepared substrate can be placed into proper propagation trays, pots and other containers according to the chosen cultivation methods.
Substrate preparation with water
Romberg POPUP BOX is supplied in a compacted form and needs to be soaked with water before its usage. The substrate is expanded after water preparation and gets ready for usage. The substrate stays compacted until its preparation, but after that it transforms into a usable substrate.
Amount of water can be adjusted during the substrate preparation according to its condition. Gradual preparation gives the opportunity to distribute water throughout the substrate evenly.
Sowing and young plants growing
A prepared substrate serves as a basis for different stages of plant development. The Romberg POPUP BOX can be used not only for seed sowing and young plants growing, but also for propagation activities, when there is a need for smaller amounts of substrate.
Seeds are placed into prepared substrate at proper depths according to the species of plant. During cultivation moisture, temperature, light and other factors are adjusted in accordance with plant needs.
Compact substrate for cultivation
Compacted and expanding after soaking, Romberg POPUP BOX combines two qualities - compactness and substrate suitability. In case there is a need to have propagation substrate always available without having a lot of loose substrate, the compact substrate will be very helpful.
Compactness of the substrate simplifies its handling before preparation. After expansion it is possible to divide the substrate between proper containers or use it right away.
Organized propagation setup
Using particular growing substrate allows creating a structured setup for starting seeds and growing young plants. The Romberg POPUP BOX can be a part of an organized propagation setup along with seed trays, pots, propagators and other equipment.
